To aZZ 'whom t may concern.'

Be it known that I, CLINTON A. HAGADONE, a citizen of the-United States, residing at Western Springs, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvesters, of which the following `is a full, clear, and eX- actspecification.

This invention relates to harvesters, and more particularly to control means therefor, the invention being especially applicable, although notlimited` to corn harvesters.

The growingtendency in the operation of harvesters is to hitch or. connect two or three together in trailing and oifset relation *behind a tractor. It has been thel general practice to have an operator upon each one of these trailing harvesters to control the movements and the operation of the various parts thereof. Such practice, however, is not economical. The preferred practice is to remotely control the movement of the harvesters and the operation ofthe various parts from a single point, preferably from the tractor. y

It, therefore, is one of the objects of this invention to control the movements of harvesters, and especially a plurality of such harvesters, being propelled, for-:exampla by a tractor. V

Another object of the invention is to control the operation of parts of the propelled harvesters in an improved manner from a point adjacent the tractor. l

Another object of my invention is to provide a control arrangement for a plurality of motor propelled vehicles adapted to meet all the requirements for. successful commercial operation.

These and other objects are accomplished b v providing. in combination, a tractor, a

plurality of associated harvesters propelled thereb v.paud means for controlling the movements of such harvesters yfrom the tractor.

The invention is illustrated on the accom` panying sheet of drawings, in which- Figure .1 is a plan view of a portion of a tractor and two trailing harvesters connected in offset relation with respect to each other and operatively connected to the traetor and embodying my invention;

Figure 21s a side elevation ofthe same y arrangement. y Figure 3 is anenlarged view of the connectionsbetween the front and rear draft members and between the adjusting lever and rear draft member;.and Fig. 4 is asection o n the line 4-4 of Fig. 3.

;The various novel features of my invention will be apparent from the following description and drawings and will be particu- .la-rly pointedout in theappended claims.

As shown in the drawings, I have pro 'vided al tractor 10 ywhich may be of any approved type` having, v'among other elements, tractionwheels 11Land a vhand steering control wheel 12, which lis located adjacent the operators seat 13. The vtractor is also pro` vided with a. draftlink 14, to which is pivotally connected the forward end of a tongue or draft member 15 of a harvester 16, which in this case is a corn harvester. The tongue or draft member' 15 takes the place of the usual tongue on the harvester and is provided'at its rear end with two extension pieces 151 which are pivotally connected at 152 to a lug riveted to the bars 154, 15*s forming the rear ydraft member of thev harvester in the samemanner that the usual tongue is connected. nected to the frame of the harvester at the front'andrear ends as shownl and both bars are connected intermediate their ends to the adjusting yoke 31 which embraces the axle 2O and transmits the pull on the tongue` and draft bars to the axle to propel the harvester. Pivotally secured to a rear portion y 17 'of the main frame of theharvester 16 is a tongue or draft. member 18 of another corn harvester 19. The tongue' 18 is pivotally connected to the second harvester by two extension pieces 182 and a pivotal kconnection 183 in the same manner that the tongue 15 is secured to the first harvester. These harvesters 16 and 19 are connected to each other and to .the tractor -in such a manner .thaiJ they are in trailing offset relation to permit the gatheringy boards 16 of the harvesters 16 and 19 to l'receive adjacent rows of corn.

Each of the harvesters is provided with the usual cutting knives 17,` actuated in the y 'usual manner v(not shown) and with hinding mechanism 1S. This construction is old in the art of corn harvesters and as no invention per se is claimed in the corn harvester features, they have not been shown in detail. An example of the prior art illustrating this construction is found in the patent to Hazell, 672.212, April 16, 1901.

The front lower ends of these gathering boards 16 and the cutting knives 17 must be tilted, as in all harvesters, to be at the proper dist-ance fro`m the ground during actual operating conditions. For this reason meansis provided for tilting the frames including the gathering boards of the harvest ers. The front harvester 16 has itsv frame arranged to be tilted about the axle 20 of the carrying wheels 21 ofthe harvester. VThe front harvester 16 is ytilted about the axle 20 by means ofv a lever 22, the frontend of which is located adjacent the operators seat- 13 in convenient reach for foot operation". This lever 22 'is 'rigidly connected to 'the draft member 153 of the front harvester 16 by` suitable members lIt 'is'y apparent, thereforefthat when the front end of the lever 22 is depressed, theA frame of the harvester kwill be tilted forwardly so that the front ends of the .gathering boards will ap'- proaeh the ground, the pivotal connection Y152 of .the tongue 15 I.to the harvester per# mitting .this tilting operaiton. 1n this connection attention is called tothe ,fact that tthe Icorn harvester 16 is so 'balanced that if 'the downward pressure is withdrawnfrom the front part ofthe lever 22, the harvester will automaticallyreturn to its initial position, as shown in Figure 2 of the drawings. '1n other words, there is suflicient weighty to the rear of the pivotal point 2() tol raiSetlie front part of the gathering boards into normal position when pressure has been relieved from l*the forward 'portion of the lever 22.l The second harvester 19, which" is in trailing relation tothe harvester 16, i'stilted rsimultan eously with the forward harvester 16 hva connection including a link 24, which is connected to an upper rear part or vertical frame portion 25 of the front harvester 16. a link 26 connecting the link 24 to av hand lever27, which is pivotally mounted :1h28 on a portion ofthe rear harvester 19. The tiltying motion is transmitted from this hand lever lto the frame l.through a member 27 xed to the lever 27 to which is pivoted a .suitable ,link 29 and member 30. connected at one end to link 29 and'secured'at 'the other which embraces lThe tiltingy vmovement of the front liarvcster 16, therefore, is transmitted directly to the. rear harvester through the'connection above described, that is to'say, when the front harvester is tilted., the harvester directly in the rear is automatically tilted at the same time.y It is tobe understood, of

course, that the detent of the hand lever 2T is either removed or the detent lever is locked in inoperative position by a band or the like 33 for holding the detent out of en gagement with the segment 34, the hand lever 27, a detent lever 32 and segment 34: on the rear machine being a part of the regu` lar equipment Vfor corn harvesters. Here also, when the front harvester has returned to its normal position, as shown inligure 2,u after having been tilted, it is to be noted that the frame of the rear harvester is free to return to its'initial position, which, as in the case of the first harvester, is caused by an excess amount of weight to the rear of the harvester axle 20] It is seen,`the`refore, thatfwhen the operator depresses the for; ward portion' of the'lever 2,2, the frame of the front harvester is tilted forwardly and 'includestwo levers 35and'36 which are preferably" pivdtally mounted uponr a bracket??? secured to the forward end of the front harvester tongue 15. One of these levers 35 is operatively connected by'a link 38,' pivotally mounted bellcra'nk 39 and link L19 to 'a standard harvestcrclutch 4-1 for 'co'ntrolling the operation of the inovablefelemeint 42 o'f the bundle carrier 43 on' the' front harvester' 1,6.: This movable element 42 is actuated Ib'y' a suitable chain or other driv- `ing"c'on`nection 44 which receives its motion from -a moving element of or on'tlie harvester through the clutchlll. 'By depress- .ing thefoot lever 35,the clutch detent 45 will`be withdrawn from'the clutch dog 46, permittingthe movable element of the cairriei' to be actuated. When the foot lever 35 isireleased. the' spring-pressed"detent 45 flies back in'to its normal position into contact with al clutch'dog ,fl-.6 to prevent transmission of motion` to the carrier 42.`1n a similar manner the other footlever 36 is connected tothe clutch' mechanism e7 of the harvester 19, the connection including the link 4S connected at one end to the Jfoot lever and atthe' other end'to a lever 49 pivoted to klthe front harvester. A ,link or cab le 50 is' connected at oneend to lever 49 and at the'cther end to' apivotally mount-ed bell crank'53'on`the `Second harvester; link 54 connects the bell crank 53 to the bell crank 51 tothe' clutch mechanism 47'.' Itis apparent therefore that by actuating the lever ,35 the carrier on the front harvester will be controlled and by actuating the other foot lever 36 the carrier 53 of the harvester' in the rear will be controlled. It is apparent also that these carriers may be actuated simultaneously or independently of each other for causing the carriers to operate simultaneously or independently.

By means of these control mechanisms for controlling` the tilting of both machines and the operation of the bundle carriers, a simple control of povver propelled associated harvesters is provided adapted to meet the various requirements for successful oommercial operation.

It is apparent that there may be various modifications of the arrangement herein shown and described, and it is my intention to cover all such arrangements Which do not involve a departure from the spirit and scope of my invention as set forth in the following claims.
